Abstract:

An assessment method of users' quality of experience (QoE) for mobile Internet based on transmission control protocol (TCP) packet layer analysis is proposed so that the metrics could be measured on the edge node of the mobile internet. This method gathers information from users' behaviors and perceptions, which could be applied to a single subscriber granularity at its best. While doing assessment in users' behaviors, the page refresh incidents should be paid more attention, which is analyzed by the TCP flags of the interaction sequence. On the other hand, users' perceptions indicators could be achieved using three different methods according to various requirements spanning from a coarsest grain perspective to a finest grain perspective, it would be later matched into a QoE mean opinion score (MOS) using the exponential independency model (IQX) of QoE and quality of service.
